Concrete Lifting and Leveling Before & After Photos

Quality 1st Basement Systems restored the sinking concrete outside of a Zarephath, NJ home. The team injected PolyLEVEL underneath the sinking slab and lifted it back up into place.

A homeowner in Basking Ridge, NJ faced safety concerns when uneven concrete around their backyard pool deck began creating hazardous walking conditions. The problem was traced to ongoing moisture intrusion and soil displacement beneath the slabs, which compromised both the stability and appearance of the deck. Seeking a reliable and professional solution, the homeowner contacted Quality 1st.

Our team conducted a detailed inspection to evaluate the extent of the settlement and identify the root causes, allowing us to develop a customized repair plan tailored specifically to address the unique challenges of this project.

To restore the pool deck, we employed our patented PolyLevel Foam Injection system, a precise and minimally invasive technique that lifts and stabilizes sunken concrete by injecting high-density polyurethane foam beneath the slabs. This method not only corrected the uneven surface but also reinforced the foundation to prevent future settling. To further protect the repair and extend the deck’s longevity, we applied our UV-resistant NexusPro Joint Sealant, sealing out moisture and preventing erosion in vulnerable joints. Additionally, Sealant Pro was applied to safeguard the concrete from stains, wear, and water damage.

The combined approach successfully restored the pool deck to a smooth, level, and safe condition with durable protection that will stand the test of time!

This homeowner in Plainsboro, NJ contacted Quality 1st Basement Systems to repair the sinking porch in the front of the home. Quality 1st was able to raise the porch back to level using PolyLevel. PolyLevel is a quick installation with lasting results, making it a better choice then removing and replacing the concrete. A small whole was drilled into the concrete and a hard foam solution is pumped into the slab which hardens and expands raising the concrete slab.  

A pool deck in Plainsboro, NJ was sinking several inches. This is a common occurance in pool decks since water that gets under the slabs can cause soil erosion, which causes the concrete to sink. Fortunately, Quality 1st Basements was able to inject PolyLevel foam into the fallen slabs of concrete. This stablized the slabs so that they would stay lifted and leveled for years to come. 

This homeowner from Wrightstown, NJ noticed sinking slabs around their pool deck. They called Quality 1st Basements for a free quote and inspection. One of our System Design Specialists recommended Polylevel foam to lift the slabs back into place. The foam expands under the slabs and expand and is strong enough to lift concrete. The homeowners can now fully enjoy their pool deck without any fear of tripping.
